I have a set of glass Costa Del Mars - they are a wrap around style and also a pair of plasic Maui Jim Sports. The Costas are amber and the Maui Jims are rose. IMO the costas are better for fishing, but it may be due to the wrap around style. The trade off is in the weight...the costas are heavy, the maui's are light. Both are high quality glasses (read - high priced anyway).

I see fish better with the costas - could be the color, could be the style?? Either way - both glasses are supposed to be "the best" - I emailed Maui Jim and told them my costa's are better.

I have never used a green shaded lens.
